I hope you all realize that you're retarded... It's from the discovery channel show, Time Warp. The guy just threw a metal ball through the bubble. There was no bullet, there was nothing going 600m/s. It's just a metal ball casually being thrown.

Just adding to your statement is all, I remember seeing this gif a couple years ago and somebody asking if any physical laws had anything to do with the fact the bullet entered and exited in perfect sync with the bubble or if it was just coincidence, and I don't think anybody ever answered him
